Abstract: A system includes a processor and a memory for evaluating a focus status of a video camera. The system receives a video image from a video server in accordance with a predetermined schedule. A selected focus classification procedure is performed on the received video image. The focus state of the video image of the video camera is classified in accordance with the focus classification procedure and determining from the video image whether the video camera is in a state of focus. A warning count is cleared when the video image is determined to be in a state of focus and an alarm indication is set when the warning count exceeds a predetermined threshold.

Abstract: A method of operating an audio system having first and second sources includes outputting a first audio signal from the first source on first and second speakers. In response to a listener input, the first audio signal and a second audio signal from the second source are output simultaneously on the first and second speakers. The first signal is output from each of the first and second speakers such that the first signal is perceived by a listener to originate from a first direction toward the listener. The second signal is output from each of the first and second speakers such that the second signal is perceived by the listener to originate from a second direction toward the listener. The second direction is offset at least ninety degrees from the first direction.

Abstract: A dual microphone near field voice enhancement arrangement in a motor vehicle includes a seat having a headrest with two opposite lateral sides. Each of two microphones is mounted on a respective one of the two opposite lateral sides of the headrest. Each microphone produces a respective microphone signal indicative of sounds within a passenger compartment. An electronic processor receives the microphone signals.

The processor applies a respective time delay to each of the microphone signals based on the calculated time delay to produce two time-aligned signals. The processor applies a respective gain to each of the time-aligned microphone signals based on the estimated amplitudes to produce two time-aligned and gain corrected signals. The processor sums the time-aligned and gain corrected signals.

Abstract: An AC capable power amplifier arrangement is realized that includes a buck converter with a power inductor, two buck switches, and alternately a buck-boost converter using four switches, each driving an output polarity steering set of four switches. The polarity steering switches convey the converter output current to output terminals that connect to a load with a capacitor connected in parallel.

A mixer receives an input voltage signal, an output of the differential receiver, and output from a triangle wave generator. A set of two comparators for buck amplifier conversion, or four comparators for buck-boost amplifier conversion, each receives an output of the mixer. Each of the comparators produces a respective output for driving the converter switches through simple steering logic interfaces between the comparators, the converter components and a polarity steering output stage.
